The 7th Concrete Design Competition on METAMORPHOSIS asks students of architecture, design and engineering to explore and exploit the potential of concrete’s properties with respect to any notion of METAMORPHOSIS. These can be related to inherent material properties as well as to concrete’s application in new or existing structures. They may address aesthetic desires, structural systems or fabrication methods and comment on economic realities, sustainability demands or social issues. Proposals may range from objects, furniture and architectural details to housing, landscape interventions, complex buildings, infrastructure and structural systems.
